INTRODUCTION

Small ubiquitin-like modifier (SUMO) is a member of the ubiquitin-like protein (Ubl) family that is covalently conjugated to cellular proteins in a manner similar to Ub-conjugation (Kerscher, O., Felberbaum, R., and Hochstrasser, M. 2006. Modification of proteins by ubiquitin and ubiquitin-like proteins. Annu Rev Cell Dev Biol. 22:159-80). Mammalian cells express three major isoforms: SUMO1, SUMO2 and SUMO3. SUMO2 and SUMO3 share-95% amino acid sequence homology but have-45% sequence homology with SUMO1 (Kamitani, T., Kito. K, Nguyen, H P., Fukuda-Kamitani, T., and Yeh, E. T. 1998. Characterization of a second member of the sentrin family of ubiquitin-like proteins. J Biol Chem. 273(18):11349-53). SUMO proteins can be conjugated to a single lysine residue of a protein (monosumoylation) or to a second SUMO protein that is already conjugated to a protein forming a SUMO chain (polysumoylation). Only SUMO2/3 can form such chains because they possess internal consensus SUMO modification sites (Tatham. M. H., Jaffray, E., Vaughan, O. A. Desterro. J. M., Botting, C. H., Naismith, J. H., Hay, R T. 2001. Polymeric chains of SUMO-2 and SUMO-3 are conjugated to protein substrates by SAE1/SAE2 and Ubc9. J Biol Chem. 276(38):35368-74). An additional isoform, SUMO4, is found in kidney, lymph node and spleen cells, but it is not known whether SUMO4 can be conjugated to cellular proteins.

SUMO1, SUMO2 and SUMO3 are activated in an ATP-dependent manner by the SUMO-activating enzyme (SAE). SAE is a heterodimer that consists of SAE1 (SUMO-activating enzyme subunit 1) and SAE2 (UBA2). SAE, like other E1 activating enzymes, uses ATP to adenylate the C-terminal glycine residue of SUMO. In a second step, a thioester intermediate is then formed between the C-terminal glycine of SUMO and a cysteine residue in SAE2. Next, SUMO is transferred from the E1 to the cysteine residue of the SUMO conjugating enzyme (E2), UBC9. Unlike the Ub pathway that contains many E2 enzymes, Ubc9 is currently the only known conjugating enzyme for SUMO and functions with SUMO1, SUMO2 and SUMO3 proteins. SUMO proteins are then conjugated to the target protein, either directly or in conjunction with an E3 ligase, through isopeptide bond formation with the epsilon amino group of a lysine side chain on a target protein. Several SUMO E3 ligases, including PIAS (protein inhibitor of activated signal transducer and activator of transcription protein) proteins and Ran-binding protein 2 (RanBP2), and polycomb 2 (Pc2), have been identified (Johnson, E. S., and Gupta, A A 2001. An E3-like factor that promotes SUMO conjugation to the yeast septins. Cell. 106(6):735-44; Pichler, A, Gast, A, Seeler, J. S., Dejean, A; Melchior, F. 2002. The nucleoporin RanBP2 has SUMO1 E3 ligase activity. Cell. 108(1):109-20; Kagey, M. H., Melhuish. T. A, and Wotton. D. 2003. The polycomb protein Pc2 is a SUMO E3. Cell. 113(1):127-37). Once attached to cellular targets, SUMO modulates the function, subcellular localization, complex formation and/or stability of substrate proteins (Müller, S., Hoege, C., Pyrowolakis, G., and Jentsch, S. 2001. SUMO, ubiquitin's mysterious cousin. Nat Rev Mol Cell Biol. 2(3):202-10). SUMO-conjugation is reversible through the action of de-sumoylating enzymes called SENPs (Hay, R. T. 2007. SUMO-specific proteases; a twist in the tail. Trends Cell Biol. 17(8):370-6) and the SUMO proteins can then participate in additional conjugation cycles.

SAE-initiated SUMO-conjugation plays a major role in regulating diverse cellular processes, including cell cycle regulation, transcriptional regulation, cellular protein targeting, maintenance of genome integrity, chromosome segregation, and protein stability (Hay, R. T. 2005. SUMO: a history of modification. Mol Cell. 18(1):1-12; Gill, G. 2004. SUMO and ubiquitin in the nucleus: different functions, similar mechanisms? Genes Dev. 18(17):2046-59). For example, SUMO-conjugation causes changes in the subcellular localization of RanGAP1 by targeting it to the nuclear pore complex (Mahajan, R, Delphin, C., Guan, T., Gerace, L., and Melchior, F. 1997. A small ubiquitin-related polypeptide involved in targeting RanGAP1 to nuclear pore complex protein RanBP2. Cell. 88(1):97-1070). Sumoylation counteracts ubiquitination and subsequently blocks the degradation of IκB, thereby negatively regulating NF-κB activation (Desterro. J. M., Rodriguez, M. S., Hay, R T. 1998. SUMO-1 modification of IkappaBalpha inhibits NF-kappaB activation. Mol Cell. 2(2):233-9). Sumoylation has been reported to play an important role in transcription exhibiting both repressive and stimulatory effects. Many of the transcriptional nodes that are modulated play important roles in cancer. For example, sumoylation stimulates the transcriptional activities of transcription factors such as p53 and HSF2 (Rodriguez, M. S., Desterro, J. M., Lain, S., Midgley, C. A, Lane, D. P., and Hay, R. T. 1999. SUMO-1 modification activates the transcriptional response of p53. EMBO J. 18(22):6455-61: Goodson, M. L., Hong, Y., Rogers, R., Matunis, M. J., Park-Sarge, O. K, Sarge, K D. 2001. Sumo-1 modification regulates the DNA binding activity of heat shock transcription factor 2, a promyelocytic leukemia nuclear body associated transcription factor. J Biol Chem. 276(21):18513-8). In contrast, SUMO-conjugation represses the transcriptional activities of transcription factors such as LEF (Sachdev, S., Bruhn, L., Sieber, H., Pichler, A, Melchior, F., Grosschedl, R 2001. PIASy, a nuclear matrix-associated SUMO E3 ligase, represses LEF1 activity by sequestration into nuclear bodies. Genes Dev. 15(23):3088-103) and c-Myb (Bies, J., Markus, J., and Wolff, L. 2002. Covalent attachment of the SUMO-1 protein to the negative regulatory domain of the c-Myb transcription factor modifies its stability and transactivation capacity. J Biol Chem. 277(11):8999-9009). Thus, SUMO-conjugation controls gene expression and growth control pathways that are important for cancer cell survival.

Altered expression of SAE pathway components have been noted in a variety of cancer types: (Moschos, S. J., Jukic, D. M., Athanassiou, C., Bhargava, R., Dacic, S., Wang, X., Kuan, S. F., Fayewicz, S. L., Galambos, C., Acquafondata, M., Dhir, R, and Becker, D. 2010. Expression analysis of Ubc9, the single small ubiquitin-like modifier (SUMO) E2 conjugating enzyme, in normal and malignant tissues. Hum Pathol. 41(9):1286-980); including multiple myeloma (Driscoll, J. J., Pelluru, D., Lefkimmiatis, K., Fulciniti, M., Prabhala, R H, Greipp, P. R., Barlogie, B., Tai, Y. T., Anderson, K C., Shaughnessy, J. D. Jr., Annunziata, C. M., and Munshi, N. C. 2010. The sumoylation pathway is dysregulated in multiple myeloma and is associated with adverse patient outcome. Blood. 115(14):2827-34); and breast cancer (Chen, S. F., Gong, C., Luo, M., Yao, H R, Zeng, Y. J., and Su, F. X. 2011. Ubc9 expression predicts chemoresistance in breast cancer. Chin J Cancer. 30(9):638-44), In addition, preclinical studies indicate that Myc-driven cancers may be especially sensitive to SAE inhibition (Kessler, J. D., Kahle, K T., Sun, T., Meerbrey, K L., Schlabach, M. R, Schmitt, E M., Skinner, S. O., Xu, Q., Li. M. Z., Hartman, Z. C., Rao, M., Yu, P., Dominguez-Vidana, R., Liang, A C., Solimini, N. L., Bernardi, R. J., Yu, B. Hsu, T., Golding, I., Luo, J., Osbome. C. K. Creighton, C. J., Hilsenbeck, S. G., Schiff, R., Shaw. C. A, Elledge, S. J., and Westbrook, T. F. 2012. A SUMOylation-dependent transcriptional subprogram is required for Myc-driven tumorigenesis. Science. 335(6066):348-53; Hoellein, A. Fallahi, M., Schoeffmann, S., Steidle, S., Schaub, F. X., Rudelius, M., Laitinen, I., Nilsson, L., Goga, A, Peschel, C., Nilsson, J. A, Cleveland, J. L., and Keller. U. 2014. Myc-induced SUMOylation is a therapeutic vulnerability for B-cell lymphoma. Blood. 124(13):2081-90). Since SUMO-conjugation regulates essential cellular functions that contribute to the growth and survival of tumor cells, targeting SAE could represent an approach to treat proliferative disorders such as cancer.

SAE inhibitors may also be applicable for the treatment of other diseases and conditions outside of oncology. For example, SUMO modifies proteins that play important roles in neurodegenerative diseases (Steffan, J. S., Agrawal. N., Pallos, J., Rockabrand, E., Trotman, L. C., Slepko, N., Illes, K. Lukacsovich, T., Zhu, Y. Z., Cattaneo, E., Pandolfi, P. P., Thompson, L. M., Marsh, J. L. 2004. SUMO modification of Huntington and Huntington's disease pathology. Science. 304(5667):100-4); Dorval, V., and Fraser, P. E. 2006. Small ubiquitin-like modifier (SUMO) modification of natively unfolded proteins tau and alpha-synuclein. J Biol Chem. 281(15):9919-24; Ballatore, C., Lee, V. M., and Trojanowski, J. Q. 2007. Tau-mediated neurodegeneration in Alzheimer's disease and related disorders. Nat Rev Neurosci. 8(9):663-72). Sumoylation also has been reported to play important role in pathogenic viral infection, inflammation and cardiac function (Lee, H R, Kim, D. J., Lee, J. M., Choi, C. Y., Ahn, R Y., Hayward, G. S., and Ahn, J. H 2004. Ability of the human cytomegalovirus IE1 protein to modulate sumoylation of PML correlates with its functional activities in transcriptional regulation and infectivity in cultured fibroblast cells. J Virol. 78(12):6527-42; Liu, B, and Shuai, K 2009. Summon SUMO to wrestle with inflammation. Mol Cell. 35(6):731-2; Wang, J., and Schwartz, R J. 2010. Sumoylation and regulation of cardiac gene expression. Circ Res. 107(1):19-29).

It would be beneficial therefore to provide new SAE inhibitors that possess good therapeutic properties, especially for the treatment of proliferative, inflammatory, cardiovascular and neurodegenerative disorders.

DETAILED DESCRIPTION

Chemical entities of the present disclosure include those described generally for formula (I), above, and are further illustrated by the classes, subclasses, and species disclosed herein. It will be appreciated that preferred subsets described for each variable herein can be used for any of the structural subsets as well. As used herein, the following definitions shall apply unless otherwise indicated.

As described herein, chemical entities of the present disclosure may be optionally substituted with one or more substituents, such as are disclosed generally above, or as exemplified by particular classes, subclasses, and species disclosed herein. It will be appreciated that the phrase “optionally substituted” is used interchangeably with the phrase “substituted or unsubstituted.” In general, the term “substituted,” whether preceded by the term “optionally” or not, means that a hydrogen radical of the designated moiety is replaced with the radical of a specified substituent, provided that the substitution results in a stable or chemically feasible chemical entity. The term “substitutable,” when used in reference to a designated atom, means that attached to the atom is a hydrogen radical, which hydrogen atom can be replaced with the radical of a suitable substituent. Unless otherwise indicated, an “optionally substituted” group may have a substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. Combinations of substituents envisioned by this disclosure are, for instance, those that result in the formation of stable or chemically feasible chemical entities.

A stable chemical entity or chemically feasible chemical entity is one in which the chemical structure is not substantially altered when kept at a temperature from about −80° C. to about +40° C., in the absence of moisture or other chemically reactive conditions, for at least a week, or a chemical entity which maintains its integrity long enough to be useful for therapeutic or prophylactic administration to a patient.

The phrase “one or more substituents,” as used herein, refers to a number of substituents that equals from one to the maximum number of substituents possible based on the number of available bonding sites, provided that the above conditions of stability and chemical feasibility are met.

As used herein, the term “independently selected” means that the same or different values may be selected for multiple instances of a given variable in a single chemical entity.

The terms “heteroaryl” and “heteroar-,” used alone or as part of a larger moiety. e.g., “heteroaralkyl,” or “heteroaralkoxy,” refer to groups having 5 to 14 ring atoms, such as 5, 6, 9, or 10 ring atoms; having 6, 10, or 14 pi electrons shared in a cyclic array; and having, in addition to carbon atoms, from one to five heteroatoms. A heteroaryl group may be mono-, bi-, tri-, or polycyclic, for instance mono-, bi-, or tricyclic, such as mono- or bicyclic. In the context of “heteroar” entities, the term “heteroatom” refers to nitrogen, oxygen, or sulfur, and includes any oxidized form of nitrogen or sulfur, and any quaternized form of a basic nitrogen. For example, a nitrogen atom of a heteroaryl may be a basic nitrogen atom and may also be optionally oxidized to the corresponding N-oxide. When a heteroaryl is substituted by a hydroxy group, it also includes its corresponding tautomer. The terms “heteroaryl” and “heteroar-,” as used herein, also include groups in which a heteroaromatic ring is fused to one or more aryl, cycloaliphatic, or heterocycloaliphatic rings. Nonlimiting examples of heteroaryl groups include thienyl, furanyl, pyrrolyl, imidazolyl, pyrazolyl, triazolyl, tetrazolyl, oxazolyl, isoxazolyl, oxadiazolyl, thiazolyl, isothiazolyl, thiadiazolyl, pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, indolizinyl, purinyl, naphthyridinyl, pteridinyl, indolyl, isoindolyl, benzothienyl, benzofuranyl, dibenzofuranyl, indazolyl, benzimidazolyl, benzthiazolyl, quinolyl, isoquinolyl, cinnolinyl, phthalazinyl, quinazolinyl, quinoxalinyl, 4H-quinolizinyl, carbazolyl, acridinyl, phenazinyl, phenothiazinyl, phenoxazinyl, tetrahydroquinolinyl, tetrahydroisoquinolinyl, and pyrido[2,3-b]-1,4-oxazin-3(4H)-one. The term “heteroaryl” may be used interchangeably with the terms “heteroaryl ring,” “heteroaryl group,” or “heteroaromatic,” any of which terms include rings that are optionally substituted. The term “heteroaralkyl” refers to an alkyl group substituted by a heteroaryl, wherein the alkyl and heteroaryl portions independently are optionally substituted.

As used herein, the terms “heterocycle,” “heterocyclyl,” “heterocyclic radical,” and “heterocyclic ring” are used interchangeably and refer to a stable 3- to 8-membered monocyclic or 7-10-membered bicyclic heterocyclic moiety that is either saturated or partially unsaturated, and having, in addition to carbon atoms, one or more, for instance one to four, heteroatoms, as defined above. When used in reference to a ring atom of a heterocycle, the term “nitrogen” includes a substituted nitrogen. As an example, in a saturated or partially unsaturated ring having 0-3 heteroatoms selected from oxygen, sulfur or nitrogen, the nitrogen may be N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in pyrrolidinyl), or NR⁺ (as in N-substituted pyrrolidinyl).

A heterocyclic ring can be attached to its pendant group at any heteroatom or carbon atom that results in a stable structure and any of the ring atoms can be optionally substituted. Examples of such saturated or partially unsaturated heterocyclic radicals include, without limitation, tetrahydrofuranyl, tetrahydrothienyl, piperidinyl, decahydroquinolinyl, oxazolidinyl, piperazinyl, dioxanyl, dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, morpholinyl, and thiamorpholinyl. A heterocyclyl group may be mono-, bi-, tri-, or polycyclic, for instant mono-, bi-, or tricyclic, and such as mono- or bicyclic. The term “heterocyclylalkyl” refers to an alkyl group substituted by a heterocyclyl, wherein the alkyl and heterocyclyl portions independently are optionally substituted. Additionally, a heterocyclic ring also includes groups in which the heterocyclic ring is fused to one or more aryl rings.

As used herein, the term “partially unsaturated” refers to a ring moiety that includes at least one double or triple bond between ring atoms. The term “partially unsaturated” is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aromatic (e.g., aryl or heteroaryl) moieties, as herein defined.

The term “alkylene” refers to a bivalent alkyl group. An “alkylene chain” is a polymethylene group, i.e., —(CH₂)_(n)—, wherein n is a positive integer, such as from 1 to 6, from 1 to 5, from 1 to 4, from 1 to 3, from 1 to 2, or from 2 to 3. An optionally substituted alkylene chain is a polymethylene group in which one or more methylene hydrogen atoms is optionally replaced with a substituent. Suitable substituents include those described below for a substituted aliphatic group and also include those described in the specification herein. It will be appreciated that two substituents of the alkylene group may be taken together to form a ring system. In certain embodiments, two substituents can be taken together to form a 3-7-membered ring. The substituents can be on the same or different atoms.

An alkylene chain also can be optionally interrupted by a functional group. An alkylene chain is “interrupted” by a functional group when an internal methylene unit is interrupted by the functional group. Examples of suitable “interrupting functional groups” are described in the specification and claims herein, and include double and/or triple bonds between carbons in the alkylene chain.

For purposes of clarity, all bivalent groups described herein, including, e.g., the alkylene chain linkers described above, are intended to be read from left to right, with a corresponding left-to-right reading of the formula or structure in which the variable appears.

An aryl (including aralkyl, aralkoxy, aryloxyalkyl and the like) or heteroaryl (including heteroaralkyl and heteroarylalkoxy and the like) group may contain one or more substituents and thus may be “optionally substituted.” In addition to the substituents defined above and herein, suitable substituents on the unsaturated carbon atom of an aryl or heteroaryl group also include and are generally selected from -halo, —NO₂, —CN, —R⁺, —C(R⁺)═C(R⁺)₂, —C≡C—R⁺—, —OR⁺, —SR^(∘), —S(O)R^(∘), —SO₂R^(∘), —SO₃R⁺, —SO₂N(R⁺)₂, —N(R⁺)₂, —NR⁺C(O)R⁺, —NR⁺C(S)R⁺, —NR⁺C(O)N(R⁺)₂, —NR⁺C(S)N(R⁺)₂, —N(R⁺)C(═NR⁺—N(R⁺)₂, —N(R⁺)C(═NR⁺)—R^(∘), —NR⁺CO₂R⁺, —NR⁺SO₂R^(∘), —NR⁺SO₂N(R⁺)₂, —O—C(O)R⁺, —O—CO₂R⁺, —OC(O)N(R⁺)₂, —C(O)R⁺, —C(S)R^(∘), —CO₂R⁺, —C(O)—C(O)R⁺, —C(O)N(R⁺)₂, —C(S)N(R⁺)₂, —C(O)N(R⁺)—OR⁺, —C(O)N(R⁺)C(═NR⁺)—N(R⁺)₂, —N(R⁺)C(═NR⁺)—N(R⁺)—C(O)R⁺, —C(═NR⁺)—N(R⁺)₂, —C(═NR⁺)—OR⁺, —N(R⁺)—N(R⁺)₂, —C(═NR⁺)—N(R⁺)—OR⁺, —C(R^(∘))═N—OR⁺, —P(O)(R⁺)₂, —P(O)(OR⁺)₂, —O—P(O)—OR⁺, and —P(O)(NR⁺)—N(R⁺)₂, wherein R⁺, independently, is hydrogen or an optionally substituted aliphatic, aryl, heteroaryl, cycloaliphatic, or heterocyclyl group, or two independent occurrences of R⁺ are taken together with their intervening atom(s) to form an optionally substituted 5-7-membered aryl, heteroaryl, cycloaliphatic, or heterocyclyl. Each R^(∘) is, independently, an optionally substituted aliphatic, aryl, heteroaryl, cycloaliphatic, or heterocyclyl group.

An aliphatic or heteroaliphatic group, or a non-aromatic carbocyclic or heterocyclic ring may contain one or more substituents and thus may be “optionally substituted.” Unless otherwise defined above and herein, suitable substituents on the saturated carbon of an aliphatic or heteroaliphatic group, or of a non-aromatic carbocyclic or heterocyclic ring are selected from those listed above for the unsaturated carbon of an aryl or heteroaryl group and additionally include the following: ═O, ═S, ═C(R*)₂, ═N—N(R*)₂, ═N—OR*, ═N—NHC(O)R*, ═N—NHCO₂R^(∘)═N—NHSO₂R^(∘) or ═N—R* where R^(∘) is defined above, and each R* is independently selected from hydrogen or an optionally substituted C₁₋₆ aliphatic group.

In addition to the substituents defined above and herein, optional substituents on the nitrogen of a non-aromatic heterocyclic ring also include and are generally selected from —R⁺, —N(R⁺)₂, —C(O)R⁺, —C(O)OR⁺, —C(O)C(O)R⁺, —C(O)CH₂C(O)R⁺, —S(O)₂R⁺, —S(O)₂N(R⁺)₂, —C(S)N(R⁺)₂, —C(═NH)—N(R⁺)₂, or —N(R⁺)S(O)₂R⁺; wherein each R⁺ is defined above. A ring nitrogen atom of a heteroaryl or non-aromatic heterocyclic ring also may be oxidized to form the corresponding N-hydroxy or N-oxide chemical entity. A nonlimiting example of such a heteroaryl having an oxidized ring nitrogen atom is N-oxidopyridyl.

As detailed above, in some embodiments, two independent occurrences of R⁺ (or any other variable similarly defined in the specification and claims herein), are taken together with their intervening atom(s) to form a monocyclic or bicyclic ring selected from 3-13-membered cycloaliphatic, 3-12-membered heterocyclyl having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, 6-10-membered aryl, or 5-10-membered heteroaryl having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur.

Exemplary rings that are formed when two independent occurrences of R⁺ (or any other variable similarly defined in the specification and claims herein), are taken together with their intervening atom(s) include, but are not limited to the following: a) two independent occurrences of R⁺ (or any other variable similarly defined in the specification or claims herein) that are bound to the same atom and are taken together with that atom to form a ring, for example, N(R⁺)₂, where both occurrences of R⁺ are taken together with the nitrogen atom to form a piperidin-1-yl, piperazin-1-yl, or morpholin-4-yl group; and b) two independent occurrences of R⁺ (or any other variable similarly defined in the specification or claims herein) that are bound to different atoms and are taken together with both of those atoms to form a ring, for example where a phenyl group is substituted with two occurrences of OR⁺

these two occurrences of R⁺ are taken together with the oxygen atoms to which they are bound to form a fused 6-membered oxygen containing ring:

It will be appreciated that a variety of other rings (e.g., spiro and bridged rings) can be formed when two independent occurrences of R⁺ (or any other variable similarly defined in the specification and claims herein) are taken together with their intervening atom(s) and that the examples detailed above are not intended to be limiting.

Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the Rand S configurations for each asymmetric center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present chemical entities are within the scope of the present disclosure. Unless otherwise stated, all tautomeric forms of the chemical entities disclosed herein are within the scope of the present disclosure. Additionally, unless otherwise stated, structures depicted herein are also meant to include chemical entities that differ only in the presence of one or more isotopically enriched atoms. For example, chemical entities having the present structures where there is a replacement of hydrogen by deuterium or tritium, or a replacement of a carbon by a ¹³C- or ¹⁴C-enriched carbon are within the scope of this disclosure. Such chemical entities are useful, as a nonlimiting example, as analytical tools or probes in biological assays.

It is to be understood that, when a disclosed chemical entity has at least one chiral center, the present disclosure encompasses one enantiomer of inhibitor free from the corresponding optical isomer, a racemic mixture of the inhibitor, and mixtures enriched in one enantiomer relative to its corresponding optical isomer. When a mixture is enriched in one enantiomer relative to its optical isomers, the mixture contains, for example, an enantiomeric excess of at least 50%, 75%, 90%, 95%, 99%, or 99.5%.

The enantiomers of the present disclosure may be resolved by methods known to those skilled in the art, for example by formation of diastereoisomeric salts which may be separated, for example, by crystallization; formation of diastereoisomeric derivatives or complexes which may be separated, for example, by crystallization, gas-liquid or liquid chromatography; selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic esterification; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support for example silica with a bound chiral ligand or in the presence of a chiral solvent. Where the desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired enantiomeric form. Alternatively, specific enantiomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer into the other by asymmetric transformation.

When a disclosed chemical entity has at least two chiral centers, the present disclosure encompasses a diastereomer free of other diastereomers, a pair of diastereomers free from other diasteromeric pairs, mixtures of diasteromers, mixtures of diasteromeric pairs, mixtures of diasteromers in which one diastereomer is enriched relative to the other diastereomer(s) and mixtures of diasteromeric pairs in which one diastereomeric pair is enriched relative to the other diastereomeric pair(s). When a mixture is enriched in one diastereomer or diastereomeric pair(s) relative to the other diastereomers or diastereomeric pair(s), the mixture is enriched with the depicted or referenced diastereomer or diastereomeric pair(s) relative to other diastereomers or diastereomeric pair(s) for the chemical entity, for example, by a molar excess of at least 50%, 75%, 90%, 95%, 99% or 99.5%.

The diastereoisomeric pairs may be separated by methods known to those skilled in the art, for example chromatography or crystallization and the individual enantiomers within each pair may be separated as described above. Specific procedures for chromatographically separating diastereomeric pairs of precursors used in the preparation of chemical entities disclosed herein are provided the examples herein.

For the avoidance of doubt, for chemical entities described herein, where the chemical entity is a single diastereomer and the absolute configuration of the chiral centers is known the name of the chemical entity reflects the assigned configuration at each stereochemical center; for example chemical entity I-43: {(1R,2S,4R)-4-[(5-{[4-(3-chlorobenzyl)-2-thienyl]carbonyl}pyrimidin-4-yl)amino]-2-hydroxycyclopentyl}methyl sulfamate. Where the chemical entity is a single diastereomer and the absolute configuration is known at some of the chiral centers but is unknown at one chiral center, the name reflects the two possibilities separated by an “or”; for example chemical entity I-1a: [(1R,2R,3S,4R)-4-{[5-({4-[(1S)-1(6-bromopyridin-2-yl)-1-hydroxyethyl]-2-thienyl}carbonyl)pyrimidin-4-yl]amino}-2,3-dihydroxycyclopentyl]methyl sulfamate or [(1R,2R,3S,4R)-4-{[5-({4-[(1R)-1-(6-bromopyridin-2-yl)-1-hydroxyethyl]-2-thienyl}carbonyl)pyrimidin-4-yl]amino}-2,3-dihydroxycyclopentyl]methyl sulfamate. Where the chemical entity is a mixture of two or more diastereomers the name reflects the two or more possibilities by using “and” between the names of the individual diastereomers that make up the mixture; for example chemical entity I-1: [(1R,2R,3S,4R)-4-{[5-({4-[(1S)-1-(6-bromopyridin-2-yl)-1-hydroxyethyl]-2-thienyl}carbonyl)pyrimidin-4-yl]amino}-2.3-dihydroxycyclopentyl]methyl sulfamate and [(1R,2R,3S,4R)-4-{[5-({4-[(1R)-1-(6-bromopyridin-2-yl)-1-hydroxyethyl]-2-thienyl}carbonyl)pyrimidin-4-yl]amino}-2,3-dihydroxycyclopentyl]methyl sulfamate.

It will be appreciated that the chemical entities of this disclosure may be derivatized at functional groups to provide prodrug derivatives which are capable of conversion back to the parent chemical entities in vivo. Examples of such prodrugs include the physiologically acceptable and metabolically labile derivatives. More specifically, the prodrug of the chemical entity of this disclosure is an ether or ester of the —OH group of the chemical entity. Prodrugs according to this disclosure include those in which R^(b) is —C(O)—R^(bx), wherein R^(bx) has the values described herein, as discussed above. Furthermore, various approaches for providing prodrugs are known to those skilled in the art, as described in, e.g., Li et al., “Prodrugs of Nucleoside Analogues for Improved Oral Absorption and Tissue Targeting,” J. Pharm. Sci. 97, 1109-34 (2008); Rautio et al., “Prodrugs: design and clinical applications,” Nat. Rev. Drug Discovery 7, 255-270 (2008); and Rautio, Prodrugs and Targeted Delivery, Wiley-VCH (2011) (ISBN-10: 3527326030).

As used herein, “crystalline” refers to a solid in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating three-dimensional pattern having a highly regular chemical structure. In particular, a crystalline compound or salt might be produced as one or more crystalline forms. For the purposes of this application, the terms “crystalline form” and “polymorph” are synonymous; the terms distinguish between crystals that have different properties (e.g., different XRPD patterns, different DSC scan results). Pseudopolymorphs are typically different solvates of a material, and thus the properties of pseudopolymorphs differ from one another. Thus, each distinct polymorph and pseudopolymorph is considered to be a distinct crystalline form herein.

“Substantially crystalline” refers to compounds or salts that are at least a particular weight percent crystalline. In some embodiments, the compound or salt is substantially crystalline. Examples of a crystalline form or substantially crystalline form include a single crystalline form or a mixture of different crystalline forms. Particular weight percentages include 50%, 60%, 70%, 75%, 80%, 85%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5% and 99.9%. In some embodiments, substantially crystalline refers to compounds or salts that are at least 70% crystalline. In some embodiments, substantially crystalline refers to compounds or salts that are at least 80% crystalline. In some embodiments, substantially crystalline refers to compounds or salts that are at least 85% crystalline. In some embodiments, substantially crystalline refers to compounds or salts that are at least 90% crystalline. In some embodiments, substantially crystalline refers to compounds or salts that are at least 95% crystalline.

The term “hydrate” includes, for example, hemihydrates, monohydrates, sesquihydrates, dihydrates, and trihydrates. In some embodiments, a hydrate, such as a sesquihydrate, may be prepared by crystallization of a chemical entity disclosed herein from ethanol/distilled water. In some embodiments, a hydrate may be prepared by crystallization of a chemical entity disclosed herein from aqueous 50 mM citrate buffer at about pH 4.5.

The term “seeding” refers to the addition of crystalline material to a solution or mixture to initiate crystallization.

Some embodiments are directed to compounds or salts wherein at least a particular percentage by weight of the compound or salt is crystalline. Some embodiments are directed to a compound or salt wherein at least a particular percentage by weight of the compound or salt is crystalline. Particular weight percentages include 10%, 20%, 30%, 40%, 50%, 60%, 70%, 75%, 80%, 85%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5% and 99.9%. When a particular percentage by weight of the compound or salt is crystalline, the remainder of the compound or salt is the amorphous form of the compound or salt. When a particular percentage by weight of the compound or salt is a designated crystalline form, the remainder of the compound or salt is some combination of the amorphous form of the compound or salt, and one or more crystalline forms of the compound or salt excluding the designated crystalline form.

When a crystalline form of a compound or salt is identified using one or more temperatures from a DSC profile (e.g., onset of endothermic transition, melt, etc.), each of the temperature values is understood to mean the given value f 2° C.

When a crystalline form of a compound or salt is identified using one or more peaks from a raman pattern expressed as cm⁻¹, it is understood to mean the given value ±0.2 cm⁻¹, unless otherwise expressed.

Solid state forms of I-257b. Provided herein is an assortment of characterizing information, which is sufficient, but not all of which is necessary, to describe crystalline Form 1 anhydrous compound I-257 (“I-257b Form 1”).

FIG. 1 shows an X-ray powder diffraction (XRPD) pattern of Form 1 of compound I-257b obtained using CuKα radiation. Peaks identified in FIG. 1 include those listed in the table below.

In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having a peak at 2θ angle 25.2°. In some embodiments. I-257b Form 1 is characterized by an XRPD pattern having peaks at 2θ angles of 25.2° and 18.6°. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having peaks at 2θ angles of 25.2°, 21.7°, 18.6°, and 14.5°. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having peaks at 2θ angles of 25.2°, 21.7°, 18.6°, 14.5°, 22.60, 20.7° and 27.9°. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having peaks at 2θ angles of 25.2°, 21.7°, 18.6°, 14.5°, 22.6°, 20.7°, 27.9°, 24.0°, 19.1°, 25.8° and 21.4°. In some embodiments, the 2θ angles given above have an error tolerance of 0.1°. In some embodiments, the 2θ angles given above have an error tolerance of 0.2°. In some embodiments, the 2θ angles given above have an error tolerance of 0.3°. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern substantially as shown in FIG. 1 .

In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having a reference peak with a 2θ angle of 14.5±0.3°, and having peaks at 2θ angles of 4.1°, 7.2°, and 10.7° relative to the reference peak. The term “reference peak” refers to a peak in the XRPD diffractogram that one skilled in the art considers as informing the polymorphic form of the material, i.e., differentiated from instrument noise. By “relative” it is meant that the observed 2θ angle of each peak will be the sum of the 2θ angle of the reference peak and the relative 2θ angle of that peak. For example, if the reference peak has a 2θ angle of 14.2°, the relative peaks will have 2θ angles of 18.3°, 21.4°, and 24.9°; if the reference peak has a 2θ angle of 14.3°, the relative peaks will have 2θ angles of 18.4°, 21.5°, and 25.0°; if the reference peak has a 2θ angle of 14.4°, the relative peaks will have 2θ angles of 18.5°, 21.6°, and 25.1°; etc. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having a reference peak with a 2θ angle of 14.5±0.30, and having peaks at 2θ angles of 4.1°, 6.2°, 7.2°, 8.1°, 10.7°, and 13.4° relative to the reference peak. In some embodiments, I-257b Form 1 is characterized by an XRPD pattern having a reference peak with a 2θ angle of 14.5±0.3°, and having peaks at 2θ angles of 4.1°, 4.6°, 6.2°, 6.9°, 7.2, 8.1°, 9.5°, 10.7°, 11.3°, and 13.4° relative to the reference peak. Any of the peaks that one skilled in the art considers as informing the polymorphic form of the material can serve as the reference peak and the relative peaks can then be calculated. For example, if the reference peak has a 2θ angle of 25.20, then the relative peaks will have 2θ angles of −3.5°, −6.6°, and −10.7° relative to the reference peak.

The term “reference peak” refers to a peak in the XRPD diffractogram that one skilled in the art considers as informing the polymorphic form of the material, i.e., differentiated from instrument noise. By “relative” it is meant that the observed 2θ angle of each peak will be the sum of the 2θ angle of the reference peak and the relative 2θ angle of that peak. For example, if the reference peak has a 2θ angle of 18.6°, the relative peaks will have 2θ angles of 19.8°, 20.8°, and 22.5°; if the reference peak has a 2θ angle of 18.7°, the relative peaks will have 2θ angles of 19.9°, 20.9°, and 22.6°; if the reference peak has a 2θ angle of 18.8°, the relative peaks will have 2θ angles of 20.0°, 21.0°, and 22.7°; etc. In some embodiments, I-256b Form 1 is characterized by an XRPD pattern having a reference peak with a 2θ angle of 18.9±0.3°, and having peaks at 2θ angles of −2.6°, −0.2°, 1.2°, 2.2°, 3.9°, and 8.1° relative to the reference peak.

Any of the peaks that one skilled in the art considers as informing the polymorphic form of the material can serve as the reference peak and the relative peaks can then be calculated. For example, if the reference peak has a 2θ angle of 21.1°, then the relative peaks will have 2θ angles of −2.2°, −1.0°, and 1.7° relative to the reference peak.

In yet another aspect, a method for treating a proliferative, inflammatory, cardiovascular or neurodegenerative disorder is provided comprising administering an effective amount of a chemical entity, or a pharmaceutical composition to a subject in need thereof. In certain embodiments of the present disclosure an “effective amount” of the chemical entity or pharmaceutical composition is that amount effective for treating a proliferative, inflammatory, infectious, neurological or cardiovascular disorder, or is that amount effective for treating cancer. In other embodiments, an “effective amount” of a chemical entity is an amount which inhibits binding of SAE.

The chemical entities and compositions, according to the method of the present disclosure, may be administered using any amount and any route of administration effective for treating the disease. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. The chemical entities of the present disclosure are frequently formulated in dosage unit form for ease of administration and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the chemical entities and compositions of the present disclosure will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disease being treated and the severity of the disease; the activity of the specific chemical entity employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific chemical entity employed; the duration of the treatment; drugs used in combination or coincidental with the specific chemical entity employed, and like factors well known in the medical arts. The term “patient,” as used herein, means an animal, for instance a mammal, such as a human.

The pharmaceutically acceptable compositions of the present disclosure can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, lotions, salves, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated. In certain embodiments, the chemical entities of the present disclosure may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg, for instance from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.

Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active chemical entities, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents, and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol. 1,3-butylene glycol, dimethylformamide, oils (for instance, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

In order to prolong the effect of a chemical entity of the present disclosure, it is often desirable to slow the absorption of the chemical entity from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the chemical entity then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered chemical entity form is accomplished by dissolving or suspending the chemical entity in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the chemical entity in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of chemical entity to polymer and the nature of the particular polymer employed, the rate of chemical entity release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the chemical entity in liposomes or microemulsions that are compatible with body tissues.

Compositions for rectal or vaginal administration are, for instance, suppositories which can be prepared by mixing the chemical entities of the present disclosure with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore meh in the rectum or vaginal cavity and release the active chemical entity.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active chemical entity is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or for instance, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

The active chemical entities can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active chemical entity may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or for instance, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

Dosage forms for topical or transdermal administration of a chemical entity of the present disclosure include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of the present disclosure. Additionally, the present disclosure contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a chemical entity to the body. Such dosage forms can be made by dissolving or dispensing the chemical entity in the proper medium. Absorption enhancers can also be used to increase the flux of the chemical entity across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the chemical entity in a polymer matrix or gel.

In some embodiments, a chemical entity of the present disclosure or a pharmaceutical composition thereof is administered in conjunction with an anticancer agent. As used herein, the term “anticancer agent” refers to any agent that is administered to a subject with cancer for purposes of treating the cancer. Combination therapy includes administration of the therapeutic agents concurrently or sequentially. Alternatively, the therapeutic agents can be combined into one composition which is administered to the patient.

In one embodiment, the chemical entities of the present disclosure are used in combination with other therapeutic agents. In some embodiments, the additional therapeutic agent is selected from other inhibitors of SAE. In other embodiments, a chemical entity of the present disclosure is administered in conjunction with a therapeutic agent selected from the group consisting of cytotoxic agents, radiotherapy, and immunotherapy. In some embodiments, the chemical entities of the present disclosure can be used in combination with a chemotherapeutic regimen for the treatment of relapsed/refractory non-Hodgkin's lymphoma including DLBCL and CLL. Chemotherapeutic regimens include, but are not limited to R-ICE (rituximab, ifosfamide, carboplatin and etoposide), R-DHAP (rituximab, dexamethasone, high-dose cytarabine and cisplatin), and R-GDP (rituximab, gemcitabine, cisplatin and dexamethasone). It is understood that other combinations may be undertaken while remaining within the scope of the invention.

Those additional agents may be administered separately from a provided combination therapy, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a chemical entity of the present disclosure.

General Synthetic Methods and Intermediates

The chemical entities of the present disclosure can be prepared by one of ordinary skill in the art in light of the present disclosure and knowledge in the art, and/or by reference to the schemes shown below and the synthetic examples. Exemplary synthetic routes are set forth in Schemes below and in the Examples.

Scheme 1 depicts the synthesis of aldehydes v. Conversion of i to the compound iii is accomplished by a palladium mediated coupling reaction with an organozinc reagent ii in suitable solvent, such as 1,4-dioxane or THF at elevated temperature or microwave irradiation (Method A). Deprotection of TBS group of iii is effected by treatment with TBAF or acid, such as aq. HCl or TFA (Method B). Further treatment with an oxidation reagent, such as MnO₂ or Dess-Martin periodinane, in DCM affords the aldehyde v (method C).

Scheme 2 depicts the synthesis of aldehydes xi Formylation of the appropriate heteroaryl vi in the presence of alkyl lithium, such as n-BuLi or t-BuLi, and DMF in THF at cold temperature gives aldehydes vii (Method D), that are then deprotected with TBAF or acid, such as aq. HCl or TFA, to afford compounds of formula viii (Method E). Formation of the methylene bromide is achieved using a suitable reagent, for example PPh₃ and CBr₄ in DCM to afford halides of formula ix (Method F). Halides ix can be subjected to a coupling reaction with boronic acid derivatives x under suitable conditions, for example Pd(PPh₃)₄, K₂CO₃ in a suitable solvent, such as a dioxane-water mixture at elevated temperature or microwave irradiation, to give compounds of formula xi (Method G).

Scheme 3 depicts the synthesis of aldehydes xiv. The appropriate boronic acid derivatives xii can be coupled with alkyl or arylhalides, such as benzyl bromide under standard Suzuki coupling conditions, such as Pd(PPh₃)₄, Na₂CO₃, dioxane % water, elevated temperature or microwave irradiation to give compounds of formula xiv (Method H).

Scheme 4 depicts the synthesis of aldehydes xvii. Lithiation of appropriate heteroaryl bromides xv using alkyl lithium, such as n-BuLi or t-BuLi, and addition of suitable aldehydes or ketones gives the alcohols xvi (Method I). Protection of the alcohol, such as with a TIPS or TBS group followed by cleavage of the acetal group using acidic conditions, such as aq. HCl/THF or Dowex resin, in suitable solvent, such as acetone, gives the aldehydes xvii (Method J). Alternatively, silyl ethers xviii are lithiated in an analogous fashion and reacted with suitable aldehydes or ketones to give alcohols xix. Protection followed by selective deprotection of the primary silyl ether with mild acidic conditions, such as 1% HCl in ethanol followed by an oxidation using Dess-Martin periodinane or MnO₂ in suitable solvent, such as DCM, gives the aldehydes xvii (Method K).

Scheme 5 depicts the synthesis of aldehydes xxiii substituted with an isochroman ring. Lithiation of an appropriate bromide xx using alkyl lithium, such as n-BuLi or t-Bull followed by addition of an aldehydes xxi gives the alcohols xxii (Method L). Under acidic conditions, such as aq. HCl/THF or TFA/water, cyclization and deprotection occur to form the aldehyde xxiii (Method M). Alternatively, deprotection of the primary silyl ethers, followed by activation of the primary alcohols, such as conversion to the iodide or mesylate, facilitates cyclization using Ag₂O or base such as NaH in suitable solvent, such as Et₂O or DMF. Deprotection of the acetals yields aldehydes xxiii (Method N).

Scheme 3b depicts an alternative synthesis of aldehydes xxviii substituted with an isochroman ring. Lithiation of an appropriate bromide using alkyl lithium, such as n-BuLi or t-BuLi, at cold temperature followed by addition of lactones xxv gives the ketones xxvi (Method O). Reduction of the ketone by reducing agent, such as NaBH₂ in a suitable solvent, such as THF, provides alcohols xxvii (Method P). Under acidic conditions, such as aq. HCl/THF or TFA/water cyclization and deprotection occur to form the aldehyde xxviii (Method Q). Alternatively, activation of the primary alcohols, such as conversion to the iodide or mesylate facilitates cyclization using Ag₂O or base such as NaH in suitable solvent, such as Et₂O or DMF. Deprotection of the acetals under acidic condition, such as aq. HCl/THF or TFA/water yields aldehydes xxviii (Method R).

Scheme 4 depicts the synthesis of aldehydes xxxii, substituted with a tetrahydroisoquinoline ring. Lithiation of an appropriate heteroaryl bromide using alkyl lithium, such as n-BuLi or t-BuLi at cold temperature and addition of dihydroisoquinolines (imine) xxix in the presence of Lewis acid, such as BF₃ Et₂O complex, gives the tetrahydroisoquinolines xxx (Method S). Protection of amines under general conditions, such as (Boc)₂O/DMAP in acetonitrile, affords carbamates xxxi (Method T). Cleavage of the acetal group using acidic conditions, such as aq. HCl/THF or Dowex resin in suitable solvent, such as acetone, gives the aldehydes xxxii (Method J).

Scheme 8 depicts the synthesis of aldehydes substituted with a pyrrolidine ring. Lithiation of an appropriate bromides using alkyl lithium, such as n-Bull or t-BuLi, at cold temperature and addition of a dihydropyrrolidines (imine) xxxiii gives the pyrrolidine intermediates xxxiv (Method U). Acetals xxxiv are treated under acidic conditions, such as aq. HCl/acetone or Dowex/acetone followed by protection of amines under usual conditions, such as (Boc)₂O, DMAP in suitable solvent, such as acetonitrile, gives the aldehydes xxxv (Method V).

Scheme 9 depicts the synthesis of aldehydes xxxviii. Alcohols xxxvii can be prepared by appropriate bromides xxiv and phenyl ketone derivatives xxxvi under an analogous reaction condition described in scheme 5 (Method L). Under acidic conditions, such as aq. HCl/THF or TFA/water, cyclization and deprotection occur to form the aldehydes xxxviii (Method M). Alternatively, deprotection of the primary silyl ethers, followed by activation of the primary alcohols, such as conversion to the iodide or mesylate, facilitates cyclization using Ag₂O or base such as NaH in suitable solvent, such as Et₂O or DMF. Deprotection of the acetals under acidic conditions, such as aq. HCV/acetone or Dowex/acetone, yields aldehydes xxxviii (Method N). Alternatively, a trityl sulfur group instead of the TBS ether group provides corresponding aldehyde xxxviii.

Scheme 10 depicts the synthesis of aldehydes xlv. Lithiation of appropriate bromides xxxix using alkyl lithium, such as n-BuLi or t-BuLi at cold temperature and addition of Weinreb amides x1 gives corresponding ketones xli (Method W). Subjecting the ketones xli to alkylation with appropriate Grignard reagents or alkyl lithium reagents in suitable solvent, such as THF, at cold temperature gives alcohols xlii (Method X). Deprotection of TBS group followed by internal cyclization under acidic conditions, such as 1% HCl in ethanol, affords tetrahydrofuran derivatives xliii (Method Y) and then deprotection of TIPS group using TBAF or acid, such as aq. HCV THF or TFA/water (Method Z), followed by oxidation by MnO₂ or Dess-Martin periodinane in suitable solvent, such as DCM, provides the aldehydes xlv (Method AA).

Scheme 11 depicts the synthesis of aldehydes xlviii. Lithiation of appropriate bromides xxiv using alkyl lithium, such as n-BuLi or t-BuLi at cold temperature and addition of sulfonamides xlvi gives the compounds of formula xlvii (Method AB). Deprotection of the acetal group under conditions analogous to those described in Scheme 5 gives the aldehydes xlviii (Method J).

Scheme 12 depicts the synthesis of aldehydes Iiii. Condensation of an appropriate ketone xix and 2-methylpropane-2-sulfinamide I using Lewis acid, such as Ti(OEt)₄ in suitable solvent, such as THF, gives the intermediates Ii. The compounds Ii are treated with MeLi at cold temperature to afford compounds of formula Iii, and deprotection of acetal group under conditions analogous to those described in Scheme 5 gives the aldehydes Iiii (Method J).

Scheme 13 depicts the synthesis of diaryl ketone intermediates Ivii. Lithiation of bis-halogenated pyrimidines or pyridines Iv can be followed by addition of the aldehydes liv to give diaryl alcohols Ivi (Method AE). Oxidation for example with MnO₂ or Dess-Martin periodinane provides diarylketones Ivii (Method AF).

Scheme 14 depicts that the diarylketones Iix can also be accessed by reaction of Weinreb amides Iviii with bis-halogenated pyrimidines or pyridines Iv (method AE).

Scheme 15 shows a synthetic route for the preparation of compounds of formula Ixi and Ixii. Diaryl ketones Ivii can be treated with an appropriate amines, such as (1R,2S,3R,4R)-1-amino-2,3-(isopropylindenyl)dihydroxy-4-hydroxymethyl cyclopentane Iix (prepared according to Claiborne, C. F. et al; PCT Application Publication WO 2008/019124) or 1× in the presence of a suitable base, such as K₂CO₃. DIEA or TEA in a polar solvent, such as iPrOH, PrOH, nBuOH or DMF (Method AG).

Alternative amines can be used in this reaction (Method AG, scheme 15) such as those shown by the general formula Ixiii and represented by Ixiv through Ixix in Diagram A below. Salts of the amine, such as the hydrochloride, can usually be used in this reaction with the appropriate equivalents of base. For amine Ixiv see: Ober, M. et al. J. Am. Chem. Soc. 2005, 127, 18143-18149; for Ixv see: Armitage, 1, et al. US Patent Application Publication 2009/0036678; for Ixvi, Ixvii, Ixix see: Biggadike, K at al. J. Chem. Soc. Perkin Trans. 1988, 3, 549-554; Borthwick, A D. et al. J Med. Chem. 1990, 33, 179-186.

Scheme 16 depicts the synthesis of di-aryl ketone intermediates Ixxiv. The alcohol intermediates Ixx can be oxidized to the aldehydes Ixxi (Method AF). The aldehydes Ixxi can be reacted with appropriate Grignard reagents or organolithium reagents to give compounds of formula Ixxii (Method AH). A suitable protection, such as TBS or TIPS group under general conditions (Method A1) and deprotection of the primary TBS ether under mild acidic conditions, such as 1% aq. HCl in ethanol, at cold temperature gives compounds of formula Ixxiv (Method AJ).

Scheme 17 depicts the synthesis of keto aryl intermediates Ixxviii. The alcohol intermediates Ixxv are activated, for example by conversion to the bromide or chloride under standard conditions, such as PPh₃ with CBr₄ or CCl₄ in suitable solvent, such as DCM, to give intermediate alkyl halides Ixxvi (Method AK) and reacted with an appropriate amines m the presence of base, such as DIEA or Et₃N to give amine derivatives Ixxvii (Method AL). Additional nucleophiles may also be employed. For example, the bromide may be reacted with an alcohol or alkoxide to give ethers. The nitrogen nucleophile may be part of an aromatic ring, for example a pyrrole, imidazole, or indole. A suitable protection/deprotection strategy such as that shown at method AJ in scheme 16 gives the intermediates Ixxviii.

Scheme 18 depicts the synthesis of keto aryl intermediates Ixxxi where V₁ is S or O. The alcohol is activated, for example by conversion to the bromide or chloride, and reacted with appropriate alcohol or thiol derivatives, such as optionally substituted phenols or benzenethiols, to give ether or thio ether intermediates Ixxxi.

Scheme 19 illustrates the syntheses of compounds with general structure Ixxxiv and Ixxxv. A two-step sequence consisting of sulfamation and deprotection completes the synthesis of ketopyrimidines (ketopyridines) Ixxxiv and Ixxxv. The acetonide can be removed under acidic conditions, such as aq. HC/THF or TFA/water, and the silyl group can be removed under acidic conditions, such as aq. HCl/THF H₃PO₄/acetonitrile or TFA/water, or by using an appropriate fluoride source, such as TBAF or TASF. If using a bis protected diol such as Ixix the silyl group (TBS) can be selectively removed from the primary alcohol (e.g. mild acidic conditions at reduced temperature, such as 1% HCl in EtOH at 4° C.) prior to sulfamation. When using amines with unprotected alcohols, such as Ixiv through Ixviii, a suitable protecting group strategy can be employed to give the desired sulfamate. For example, protection of the free alcohols can be accomplished by prolonged treatment with TBSCl in DMF, which is then subjected to selective deprotection of the primary silyl group with mild acid at reduced temperature. Subsequent sulfamation and deprotection provides the desired sulfamate.

A selective sulfamation procedure can also be employed such as shown in scheme 11. The procedure employs a modified Burgess reagent (Armitage, I. et al. Org. Lett. 2012, 14, 2626-2629) followed by treatment with acid to deprotect the sulfamate (Method AO).

Analytical Methods

NMR conditions: ¹H NMR spectra are run on a 400 MHz Bruker unless otherwise stated.

Lcms Conditions:

LCMS spectra are recorded on a Hewlett-Packard HP1100 or Agilent 1100 Series LC system connected to a Micromass mass spectrometer using reverse phase C18 columns. Various gradients and run times are selected in order to best characterize the compounds. Mobile phases are based on ACN/water gradients and contain either 0.1% formic acid (methods indicated FA) or 10 mM ammonium acetate (methods indicated AA). One example of a solvent gradient that is used is 100% mobile phase A (mobile phase A=99% water+1% ACN+0.1% formic acid) to 100% mobile phase B (mobile phase B=95% ACN+5% water+0.1% formic acid) at a flow rate of 1 mL/min for a 16.5 min e.

One of ordinary skill in the art will recognize that modifications of the gradient, column length, and flow rate are possible and that some conditions may be more suitable for compound characterization than others, depending on the chemical species being analyzed.

Example 215: SAE HTRF Enzyme Assay

The SAE enzymatic reaction totals 50 μl and contains 50 mM HEPES Hemisodium (pH 7.5), 0.05% BSA 5 mM MgCl₂, 0.5 μM ATP, 250 μM GSH, 0.01 μM Ubc9-GST, 0.125 μM Sumo-Flag and 0.11 nM recombinant human SAE enzyme. The enzymatic reaction mixture, with and without inhibitor, Is incubated at 24° C. for 105 min in a 384-well plate before termination with 25 μM of Stop/Detection buffer (0.1M HEPES Hemisodium pH 7.5, 0.05% Tween20, 20 mM EDTA, 410 mM KF, 0.53 nM Europium-Cryptate labeled monoclonal anti-Flag M2 Antibody (CisBio International) and 8.125 μg/ml PHYCOLINK goat anti-GST allophycocyanin (XL-APC) antibody (Prozyme)). After incubation for 2 hours at 24° C., quantification of FRET is performed on the Pherostar™ (BMG Labtech). Percentage inhibition values at a single concentration or enzyme inhibition (IC₅₀) values are determined from those curves. One skilled in the art will appreciate that the values generated either as percentage inhibition at a single concentration or IC₅₀ values are subject to experimental variation.

Example 216: Cell Viability Assay

The cell viability assay is used to measure the effect of various compounds on cancer cell proliferation. Promega's CellTiter-Glo® Luminescent Cell Viability Assay is used to measure ATP concentration present in all metabolically active cells and the concentration declines rapidly when cells undergo necrosis or apoptosis.

The cancer cell lines of interest are propagated in recommended growth medium (Invitrogen) containing 10% Fetal Bovine Serum (Hyclone or ATCC) and 100 I.U·Penicellin/100 μg/mL Streptomycin (Invitrogen) and kept in tissue culture incubator at 37° C. with 5% CO₂. On day 1, attached cells are trypsinized with 4.5 mL of 0.25% Trypsin-EDTA (Invitrogen) at 37° C. for 2 minutes or until cells have detached. Suspension cells are collected and washed. Desired number of cells are cultured in 25 μL of media per well in tissue culture-treated black-walled, clear bottom 384-well plates (BD Biosciences) for 16-24 hours. The exact number of cells per well are optimized for each individual cell line. On day 2, 62.5 nL test compounds in DMSO (ranging from 10 mM to 508 uM in 10 point 3-fold dilution series) are directly added to cells in 384-well plate using Echo liquid handler (Labcyte). This results in a final concentration range of 0.0013 to 25 μM in 3-fold dilutions in the cell plates. On day 5 after 72 hour of incubation in tissue culture incubator, 25 μL CellTiter-Glo® (Promega) are added to the compound treated cell plates. The cell plates are incubated at room temperature for 15 min and then read luminescence on Pherastar plate reader (BMG). The test compound concentration versus cell viability curves are generated using percentage of survival calculated from luminescence readout relative to DMSO and media only controls. The percentage growth inhibition values at a single concentration (LD₅₀) values are determined from the curves.

Example 217: In Vivo Tumor Efficacy Model

SAE inhibitors are tested for their ability to inhibit tumor growth in standard xenograft tumor models. For example, HCT-116 cells (1×10⁶) in 100 μL of phosphate buffered saline are aseptically injected into the subcutaneous space in the right dorsal flank of female CD-1 nude mice (age 5-8 weeks, Charles River) using a 23-ga needle. Beginning at day 7 after inoculation, tumors are measured twice weekly using a vernier caliper. Tumor volumes are calculated using standard procedures (0.5×length×width²). When the tumors reach a volume of approximately 200 mm³, mice are randomized by tumor volume into treatment groups and injected subcutaneously with test compound (3M) μL) at various doses and schedules. All control groups receive vehicle alone. Tumor size and body weight are measured twice a week, and the study is terminated when the control tumors reach approximately 2000 mm³. Analogous procedures are followed for colon (colo205 or HCT-116 cells), AML (THP-1 or HL-60 cells), DLBCL (Ly10 or WSU-DLCL2), melanoma (A375 or A2058 cells) and lung (H460 cells) tumor models.
